Tech support scams, which get people to pay for fake computer help or steal their personal information, are convincing. You might already know the signs of a tech support scam, but do your friends and family?

You’re working on your computer when, suddenly, a message pops up on the screen: “Virus detected! Call now for a free security scan and to repair your device.” That’s a tech support scam. Don’t call, text, or email. Legit tech support companies don’t operate that way.
